To all whom it'mag concern Be it known that I, EDWARD a citizen of theUnited States, and resident of Boston, county of Suftoll'r, State ofMassachusetts, have invented an Improvement in Spinning Rings, of whichthe following description, in connection with the accompany- 7 ingdrawing, is a specification, like characters on the drawing representinglike parts.

This invention relatesto spinning rings or that type which include acasing or holder which is provided with a bearing member or lining ofselt-lubricating material, and an annular traveller operating within theeasing. Spinning rings of this type are illustrated in United StatesPatents Numbers, 857,535, dated J une '18, 1907, 874,429, dated December24:, 1907, 957,759, dated May 10,

1910 and "1,333,072, datedMarchQ, 1920.v

One of the objects of the'present invention is to improve spinning ringsof the above mentioned type by providing a spinning ring which can bemanufactured at a considerably less cost that the spinning rings.illustrated insaid patents. 7

Another object of the invention is to provide an improved spinning ringof this type which comprises fewer parts and is simplified inconstruction. i p

Another object of the invention is to provide a spinning ,ring of thistype which has an improved casing, an improved manner 01 supporting andretaining the traveller, an improved traveller in which the stemcarrying the guide eye has an inclination to the plane of the travellerand other features otimportance all as will be more fully hereinaftersetforth. In orderto give an 'derstanding ot'my invention I haveillustrated in the drawings a selected embodiment thereof which will nowbedescribed after whichthe. novelfeatures will be pointed ou't'inthe'appended claims. 1 I 1.

Fig. 8 is a fragmentary view of the lining member showing the manner inwhich the supporting pins are connected thereto.

In my present invention I have simplified the construction of the holderor casing in which the traveller is received by making it of'a basemember, an upper member which is frictionally held to the base memberand a s'elfdubricating bearing member which is received between the basemember and the upper member. 1 indicates the base member of the casing,7 indicates the upper member of the casing, 8 indicates a lubricatinglining member and 9 indicates the traveller.

This base member 1 is formed with a base flange 2 adapted to rest on andbe secured to the ring rail of the spinning frame. This flange'willpreferably be provided with a plurality of notches 3 to receive screwsor other fastening means for retaining the base to the ring rail. Thebase member is an annularmember provided with central opening 5 and itis made of sheet metal which is deformed by means of suitabledies so asto present the inwardly-directed supporting flange l that is situatedabove the base flange 2 and which constitutes a support. for the sell"-lubricating .member. The base member is also deformed to present the.annular rib 6 which'constitutes the portion to which the upper member7issecured. This upper member 7 is an annular member and is formed fromsheet metal, it being provided with the side walls 10 andtheinwardly-directed flange 11 at its upper end. The lower end of the sidewalls 10 are so arranged so that they can be snapped over orfrictionally secured to the bead '6 of the base member.

This is accomplished bycrimping inwardly certain parts of the lower edgeof the member 7 as shown at 12,such inwardly-clamped por- 'tions' beingconstructed so that they may be to or removed from the base member 1.The

outwardly-bent portions '13 also provide spaces 14 between the stemandthe flange 2 into which an implement may be inserted for prying themembers 1 and? apart.

The lining member 8 is made of some selflubricating material such forinstance as wood treated in oil and it is confined between the flange 4or'ithe base member and the flange 11 of the upper member as clearlyseen in Fig. :5. This lining memberis an annular member and is formedwith the space 15 in which the. traveller 9 received and is alsoprovided with the inwardly directed'fla'nge portion 16 which overliesthe traveller 9 and the under face. 17 of which forms a bearing for thetraveller when the latter is raised. The traveller 9. is of the annulartype and is provided with the stem 18 which extends upwardly through thebearing member and is formed with a guide eye 19 at its upper end. 7

In my present inventionthestem 18 is inclined to the plan: of thetraveller, the inclination being such thatthe st'eminclines forwardlytoward the direction in which the traveller is rotating. This is. seenin Fig. 7. The purpose of thisconstruct-ion is toso distribute thestrain of the yarn on the traveller that it will not tend to distortthetraveller as is thecase where the stem extends vertically. Thesetravellers are made. or" quite thin stock and the strain of the yarntends 'to throw the stem out of a rue vertical position and thus distortthe body of the traveller. "I find that by. making the st'zm withthi'sinclination such tendency is largely eliminated; When the spinningring isv in use the traveller is rotating rapidly in the space '15 andtlie'strain of the yarn tends to keep it at the upper portion of suchspace adjacent "the surface 17. Some means hastob'e provided, however,for supportingfthe traveller when the spinning ring is idle or atrestand in my present-construction suchsupport is secured to'and sustainedby the lining member 8Q While various types "ofsupporting the travellerfrom the lining member may be employed without departing from myinvention yet the construction illustrated herein is a simple one whichhas the'advantages that it is'ine'xpensive to manufacture. that itprovidesforeasy. removal from the lining memberor insertion of thetraveller in its place, and it'is sel-f cl'eaning and does not collectlint. Said traveller sup port comprises a plurality of arms 20 which arecarried by the liningmember and projected sufiiciently, int-o thesp'ace-15; to constitute a support forthe traveller. I prefer t placethese-supporting pins'so that'they have a tangential arrangementrelative to the traveller as indicated. best in Fig. ,4, the

free ends of said pins being pointed in'the direction in which thetraveller is rotating which in F 4 would be in the direction of thearrow. Such pins furnish a suitable support for the traveller but theyleave the space beneath the traveller open and free so that any lintwill -be freely discharged from said space. Owing'to the tangentialarrangement of the pins or arms 20 and their relation to the directionof rotation of the traveller there is no possibility that any lint willcollect on the arms for if any lint should find itsway into the space 15such lint will be wiped off the arms by the rotary motionof thetraveller" and will be discharged at the free open space at the bottomofthe spinning ring.

In order to facilitate the removal of the traveller from thelining'mrniber '8 or its insertion into place I propose to pivotallymount the arms 20 in the lining member so that they can be swung backinto the dotted line position Fig. .1 when the lining is removed fromthe casing. For this purpose each armis provided with the laterally bentend 21 which is inserted into and pivotally mounted in a bore 23 formedin the lining member. The lining member is formed with the notch 22 atthe point where each arm is pivotally connected thereto and thebore 23into which the end 21 is recrived extends from one wall of the notch.The lining member is'grooved as shown at 24: to receive the arm when thelatter is'in its operation position, the groove b;=ing of suflic'i'en'tdepth so that the arm is entirely above the plane ot the lower face or"the lining member. 50 long as the arms are in tl'ieiull line positionFig. 4 they, are operative to hold the traveller in position but byswinging'two or more. of 1 the arms backwardly, into the dotted linesposition the traveller is free to beremoved Irom the lining member.

s It will be noted that the spinning ring holdero'r casing in which thetraveller is received comprises merely the base member 1, the uppermember 7 'andthe lining member 8. holder therefore *has a minimum numberof parts which is conducive to cheapness of manufacture. Furthermore themanner in which the parts are con structed reduces the costofmahufacture.
